,iL/"o all whom @may concern."

Be it lmown that I, Gammes T. EAMES, a citizen of the United States,residing at the city of Kalamazoo, county of Kalama- Zoo, and'State ofMichigan, have invented certain new and useful. Improvements. in ArborPresses or Rams, o' which theitollowing is a specification.

`This. invent-ion relates to improvements arbor presses.

The main objects of this invention are: First, to provide a quick acting'arbor prese of the rack and pinion type. Second, to

. provide an improved pawl and ratchet means for actuating the ram of anarbor press so that it can be operated. fast or slow, with acorresponding variation oi 'power. Third,'to provide means of adjust;l'ing the tableur Work support for such an arbor press.

Objects pertaining to details andfecono mies of construction willdefinitelyl appear from the detailed description to follow.

I. accomplish the objects o f my invention by the devices and mea-nsdescribed .in the following specification.

The invention is clearly defined and 'pointed out in the claims.

A structure constituting an effective and referred embodiment of my'invention is learly illustrated in the accompanying drawing, forming apart of this specifica tion, in which:

Figure I is a perspective view of an arbor press, part of the operatinglever being broken'away. Fig. II is an enlarged front elevation View ofthe press a peering in Fig. I. Fig. III is an enlarge detail perspectiveview from the left hand side or Vthe structure appearing in Fig. I.

Fig. is anenlarged detail sectional View taken on ,a line corresponding to lineviO--il ci Fig. Il, showing the locking' means for locking the ram in theelevated position, or in any other position desired.'

Inthe drawing, the sectional views are A vtaken looking in the directionof the little. arrows at the ends of the section lines, and Similarnumerals of reference refer .to sinii lar parts throughput the severalviews,
